Mr. Robinson has 20 students in his martial arts class. The ratio of boys to girls is 4:1. How many boys and girls are in Mr. Robinson's class?

A. 15 boys, 5 girls
B. 5 boys, 15 girls
C. 16 boys, 4 girls
D. 4 boys, 16 girls

Which of the following equations is an example of the distributive property?

A. (5)(3) = (3)(5)
B. 5 + 3 = 3 + 5
C. (5)(1+2) = (5)(1) + (5)(2)
D. 15 = 15

Ratio - 4:1

thus, 4x + 1x = 20 5x = 20
thus, x = 20/5 = 4
thus, x = 4 and, 4x = 16
Thus, the answer is (C) 16 boys and 4 girls

According to distributivity, a(b+c) = ab + ac

Thus, the answer is (C)
